The conversations apparently took place when Will helped out Britney during the house judges segment of the show.

"There were rumours earlier this summer that the pair were going to duet but it wasn't until this week that Britney and Will had the discussion," a source told The Sun. "He's been trying to get them together since before he came on board as Cheryl's manager."

Will has already recorded a new collaboration himself with the 'Criminal' singer for his forthcoming record '#willpower' and is said to be working on production duties for Britney's new album.

"He told Britney he was writing a great new track and wanted his 'two favourite girls' to record it together at his home studio," declared the insider.
